Convert the ladder logic to a flow chart, then convert the flow chart to the new PLC using Function Block's.

Can you define your project requirements in more detail ?
For example what form is the source plc code in ? (e.g. a print out, vendor specific files ?) What will be doing the conversion process (e.g. a computer program, you ?) How will the projects success be tested ? |

Surely in your training you have been taught how to make a basic flow diagram!
